The InkEx Class
This class can be thought of as an extension of the Ink class. It comprises one static method.
AddStrokesAtRectangle
public static Strokes AddStrokesAtRectangle (Ink ink, Strokes strokes, Rectangle rectDestination)
This method provides the same functionality as the Ink class s AddStrokes AtRectangle, except that it returns a Strokes collection that references the newly added ink.
